Quote:Patch Tuesday was two weeks ago, and that's when all supported versions of Windows 10 got their mandatory monthly cumulative updates. As is common though, Microsoft releases new updates throughout the month, although these updates are optional. Today, cumulative updates are rolling out to Windows 10 versions 1809, 1803, 1709, and 1607.
 
This leaves out the two newest versions, 1909 and 1903, and the oldest version, 1507, which is still supported on the Long-Term Servicing Branch. Version 1511 is the only version of Windows 10 that isn't supported anymore at all, and version 1703 is only supported for Surface Hub.

• If you're on Windows 10 version 1809, you'll get KB4537818, which brings the build number to 17763.1075. You can manually download it here,
  
• Windows 10 version 1803 isn't supported on Home or Pro SKUs, but if you're on Enterprise or Education, you'll get KB4537795, which brings the build number to 17134.1345. You can manually download it here,
  
• For Windows 10 version 1709, you'll get KB4537816, bringing the build number to 16299.1717. You can manually download it here,
  
• Finally, Windows 10 version 1607 is only supported in the Long-Term Servicing Branch and for Windows Server 2016 customers, but those users will get KB4537806, bringing the build number to 14393.3542. You can manually download it here,
  

As always, you can install these updates manually, but you can also get them via Windows Update. They won't be installed automatically though. You'll need to go into Windows Update and choose to install the optional updates. If you choose not to take them, these fixes will be bundled into next month's Patch Tuesday updates.
